Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S03F11R5V are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 11.5 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 0603 (1608 Metric)
• Number of terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Composition: Thick Film

All identified substitute parts meet these core requirements. Variations in physical dimensions (length, width, height) within standard 0603 tolerances and differences in specific features (anti-sulfur vs. moisture resistant) do not affect functional interchangeability for this application category.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components with ROHS3 compliance and REACH unaffected status, meeting the same regulatory requirements as the primary part ERJ-S03F11R5V.

For automotive applications requiring AEC-Q200 qualification, the following parts are suitable: ERJ-3EKF11R5V (Panasonic), CRCW060311R5FKEA (Vishay Dale), and RMCF0603FT11R5 (Stackpole Electronics Inc).

For non-automotive applications or where moisture resistance is prioritized, CR0603-FX-11R5ELF (Bourns Inc.) and RC0603FR-0711R5L (YAGEO) are qualified alternatives.

Component selection should consider inventory availability, supply chain lead times, and specific application environmental requirements. All parts maintain identical electrical performance and package compatibility within 0603 standard tolerances.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF11R5V replace ERJ-S03F11R5V directly?

A: Yes. Both parts are manufactured by Panasonic, share identical electrical specifications (11.5 Ω ±1%, 0.1W), operate across -55°C to 155°C, and are packaged in 0603 (1608 Metric). The primary difference is the absence of anti-sulfur coating in the ERJ-3EKF series. For applications not requiring anti-sulfur protection, this substitution is functionally equivalent.

Q: Are the Bourns CR0603-FX-11R5ELF and YAGEO RC0603FR-0711R5L suitable for automotive applications?

A: CR0603-FX-11R5ELF and RC0603FR-0711R5L are not AEC-Q200 qualified. For automotive applications requiring AEC-Q200 certification, use ERJ-3EKF11R5V, CRCW060311R5FKEA, or RMCF0603FT11R5.

Q: What are the physical dimension differences between substitute parts?

A: All parts conform to 0603 (1608 Metric) package standard. Minor variations exist: CRCW060311R5FKEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" max height, while most others measure 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" max height. These variations fall within standard 0603 tolerances and do not affect PCB layout or reflow compatibility.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All listed parts, including the primary ERJ-S03F11R5V, have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture precautions are required during storage or handling.

Q: Which substitute part has the highest inventory availability?

A: RC0603FR-0711R5L (YAGEO) has the highest inventory with 68,419 pieces in stock, followed by ERJ-3EKF11R5V (Panasonic) with 163,960 pieces.
